Sweeten Company had no jobs in progress at the beginning of March and no beginning inventories. The company has two manufacturing departments--Molding and Fabrication. It started, completed, and sold only two jobs during March—Job P and Job Q. The following additional information is available for the company as a whole and for Jobs P and Q (all data and questions relate to the month of March):

Sweeten Company had no underapplied or overapplied manufacturing overhead costs during the month.

Required:

For questions 1-8, assume that Sweeten Company uses a plantwide predetermined overhead rate with machine-hours as the allocation base. For questions 9-15, assume that the company uses departmental predetermined overhead rates with machine-hours as the allocation base in both departments.

1. What was the company’s plantwide predetermined overhead rate? (Round your answer to 2 decimal places.)

	Molding	Fabrication	Total
Estimated total machine-hours used		2,500			1,500			4,000
Estimated total fixed manufacturing overhead	$	11,250		$	15,750		$	27,000
Estimated variable manufacturing overhead per machine-hour	$	1.90		$	2.70

Solution

Answer 1. Predetermined Overhead Rate - Fixed Overhead = $27,000 (Total Overhead) / 4,000 Mach Hrs Predetermined Overhead Rate - Fixed Overhead = $6.75 per Mach Hr Total Predetermined Overhead Rate = $6.75 (Fixed) + $1.90 (Variable - Molding) + $2.70 (Variable - Fabrication) Total Predetermined Overhead Rate = $11.35 per Mach.
